"I went to put my finger in its mouth and it was all resistance," he told the station. "And I'm like, 'This is a doll.'"

The doll is one of approximately 40 owned by Vermont resident Carolynne Seiffert, according to WMUR. She collects dolls to help her deal with the death of her son, the station reported. The doll in the car was named "Ainsley," and is worth more than $2,000, the station reported.

"I've been laughed at and embarrassed by all the fuss," she said in a statement to WMUR. "You can't know how people choose to deal with their losses in life."
